Our team provides continuous monitoring, threat detection, incident response, and vulnerability management across cloud and on-premises environments, including AWS, Azure, GCP, Oracle Cloud, and SaaS platforms.

Leidos is seeking a Data Security Engineer to build, optimize, and sustain the cybersecurity data pipelines that power these defensive operations. You will ingest, normalize, enrich, and manage high-volume security telemetry within Elastic; optimize data performance and quality; automate workflows; and troubleshoot dependencies across Elastic, Kafka, and CI/CD systems. You will partner with cyber teams to ensure analysts and defenders have reliable, analytics-ready data for threat detection and response.

This position is hybrid on-site 3 days/week in Adelphi, Maryland and requires U.S. Citizenship and an active TS/SCI clearance.

  • Maintain index templates, mappings, schemas, and data models supporting analytics and detection logic.

  • Implement data validation, deduplication, and quality controls to ensure data integrity.

  • Automate ingestion, transformation, and engineering workflows using Python, Bash, and related tools.

  • Monitor pipeline and indexing performance, troubleshoot data-flow issues, and optimize throughput, storage, and query performance.

  • Maintain traceability and troubleshoot dependencies across Kafka, Elastic, and CI/CD tooling.

  • Partner with Detection Engineering, Threat Analysis, Endpoint, and other cyber teams to support operational requirements.

  • Maintain technical documentation, SOPs, and engineering artifacts.

Basic Qualifications:

  • 3+ years of data engineering, data analysis, cybersecurity data engineering, or related experience.

  • Experience with data ingestion, transformation, normalization, or high-volume data-processing pipelines.

  • Experience with relevant technologies such as Elastic Stack, Kafka, Python, Bash, and CI/CD tooling.

  • Familiarity with Elastic Common Schema (ECS) or similar cybersecurity data models.

  • Required DoD 8570/8140-aligned and CSSP Analyst certifications, as applicable to the position.

  • U.S. Citizenship with an active TS/SCI clearance.

  • Strong written and verbal communication skills.

Preferred Qualifications:
  • Experience onboarding and normalizing high-volume cybersecurity telemetry and log sources.

  • Experience with Kafka, Python/Bash automation, CI/CD, or DevSecOps practices.

  • Experience supporting AWS, Azure, GCP, Oracle Cloud, hybrid-cloud, or multi-cloud environments.

  • Knowledge of cybersecurity operations, including SIEM, threat detection, incident response, and security monitoring.

  • Experience supporting a DoD CSSP, SOC, or other large-scale defensive cyber operations environment.

  • Strong troubleshooting skills across complex data pipelines and interconnected systems.
